已有的研究表明，Fe3+羧酸盐络合物具有光催化降解有机物的性能[1-3]；当草酸铁络合物体系中存在一定量的H2O2时，在太阳光或紫外光照射下，可发生类Fenton反应产生羟基自由基[4]，而草酸铁络合物可在一定程度上循环利用，使Fe3+和C2O2-4可以重新形成草酸铁络合物：2[Fe(C2O4)n](3-2n)hν2Fe2++(2n-1)C2O42-+2CO2(1)Fe2++H2O2

Maximum gallic acid yield ( 83.8%) was obtained after Escherichia coli was cultivated aerobicly in 100mL liquid culture medium with 7g/L tara tannin extract and 1g/L complementary urea on snaker (120 rpm) at initial pH 6.0 and 28℃for 28h, while maximum tannin reduction rate (43.6%) was obtained after 5g/L glucose was supplied instead of urea in the same degrading conditions above.

The Fe^0 concentration and pH had optimal values during the decolorization of X-BR in Fe^0-anaerobic biological system. When Fe0 dose, initial pH value and X-BR concentration were 400 mg/L, 7 and 100 mg/L respectively, the decolorization rate of X-BR in the integrated system could reach up to 90% after 68 h reaction. Compared with pure Fe^0 and pure microorganism treatment systems, it could be improved about 40% under the same experimental conditions. In addition, the analysis result of UV-vis spectrogram indicated that Fe^0 could promote effectively biodegrading of anthraquinone dye X-BR and its intermediate products.
